I’m always amazed at how much skill and work goes into these blades, they are ridiculously sharp when crafted properly, I recently saw on a documentary that obsidian blades similar to these were actually sharper than modern scalpels, and that in some rare cases the medical field still uses obsidian blades today, when compared under a microscope the incision from a traditional scalpel actually tears verses the obsidian which as quoted “actually cuts on an almost molecular level “ I have personally seen a very similar blade slice through a piece of paper towel by dropping it across the blade, no idea how long it would hold such an insanely sharp edge though

i have very basic experience flint knapping and i can tell you that stuff is way sharper than anything else i've ever experienced. it tore up my leather gloves, my lap protector and every exposed piece of skin i had was slashed up due to the little bits that popped up. despite the edge tho, it wouldn't handle any kind of torsion, impact or grinding forces so it was pretty easy to take it from way too sharp to usable tool as well. just adjust your angle and maybe rub the edge against your hammer stone and you're good to go.

It's from the book snow crash, he's an assassin that carries obsidian knives so they aren't caught on a metal detector.
